Java Web Service MTOM Streaming w/ WCF Client

[agolia]

I am trying to develop a webservice that uses MTOM in streaming mode for large files. The webservice appears to be configured correctly however when attempting to upload/download a file the WCF client sends/receives a byte array which is buffered into memory. For small files this is fine however large files consume large amounts of memory on the client. I have edited the binding generated from the WSDL and set transferMode = "Streamed" but this does not appear to have any affect.

Can anyone point to anything that may shed light on the issue or know if this is even possible? Thanks in advance.
